Definitions
- the present invention has been devised with the general objects of providing a machine which is particularly efficient in the production of tubes wound from strip, and a method of making such tubes.
- Other objects achievable in preferred embodiments of the invention are to provide such a machine which may be quickly and easily modified to produce such tubes of different diameters, which is particularly compact and so well suited for lowering into a manhole for the production of a tube projected as a liner into a sewer, and which, though simple and economical to manufacture, is sturdy and durable in use.
- a machine for winding tubes from strip including a base; a substantially cylindrical core mounted rotatably on the base and defining the internal diameter of a tube to be formed; means for rotating the core; an annular outer sleeve mounted on the base coaxially about the core and forming an annular space between them; an inlet opening in the sleeve to the annular space; means for guiding a tube forming strip through the inlet opening to the annular space; a series of pressure rollers mounted on the sieve in a helical path and entering the annular space to urge the strip into frictional engagement with the rotating core and to guide it to form about the core a helix with closely adjacent convolutions; locking means being provided for locking together the said adjacent convolutions.
- the strip is formed with longitudinal side ribs and a series of intermediate ribs between and parallel to them, and the adjacent side ribs of succeeding convolutions are locked together by a longitudinal grooved or recessed locking strip guided through the inlet opening and acted on by the pressure rollers to engage on and lock together the said adjacent side ribs.
- Means are preferably provided for introducing glue to the longitudinal groove or recess of the locking strip before its entry to the inlet opening.
- the core and the assembly of the outer sleeve and pressure rollers are preferably interchangeable with others for the production of tubes of different diameters.
- FIG. 1 is a partly broken-away side elevational view of a machine according to the invention
- FIG. 2 is a partly broken-away plan view of the machine
- FIG. 3 is an end elevational view of the machine
- FIG. 4 is a sectional view of the lower part of the machine taken along line 4-4 in FIG. 2;
- FIG. 5 is a detail drawing, to enlarged scale, of a pressure roller of the machine and strips interlocked thereby; and
- FIG. 6 is a sectional view, to larger scale, along line 6-6 in FIG. 1.
- the machine illustrated includes an upright base plate 10 having at its top corners shackles 11 to which are attached cables 12 from a winch or the like (not shown) by means of which the machine may be lifted and lowered, for example, into a man-hole.
- the base plate 10 is apertured to accept the housing 13 for the bearings of a main shaft 14, the housing extending forwarddly of the base plate 10 and having a peripheral flange 15 bolted to the rear face of the base plate.
- a double sprocket 16 is keyed on the rear end of the main shaft 14, and an annular mounting plate 17 is welded or otherwise secured on the front part of the shaft.
- a cylindrical outer sleeve 18 is fixed on the front face of the base plate 10, coaxially with the main shaft 14, the sleeve having at its rear end an internal flange 19 which is bolted to the base plate.
- the bottom of the outer sleeve 18 is level with the bottom edge of the base plate 10.
- a cylindrical core 20 is rotatably mounted coaxially within the outer sleeve 18 so that an annular space 21 is formed between them.
- the core is divided by an annular median plate 22, which is engaged on the front end of the main shaft 14 and bolted to its mounting plate 17.
- a section of the periphery of the core 20 is slightly reduced in diameter to form a seating for a rubber or like girdle 23, formed with a tread which is hereinafter described, and which has an outer diameter slightly greater than that of the remainder of the core 20 the surface of which , in front of the girdle , is of polished steel.
- a hydraulic motor 24 is mounted in front of the base plate 10 on an adjustable carrier bracket 25, the motor shaft 26 passing through a slotted hole in the carrier plate to carry, behind the base plate, a double sprocket 27 connected by endless chains 28 to the double sprocket 16 on the main shaft 14.
- the motor shaft 26 also carries a sprocket 29 connected by a chain 30 to a sprocket 31 on the shaft of a glue pump 32 mounted on a bracket 33 fixed on the front of the base plate 10.
- the outer sleeve 18 is formed with a series of openings 34 arranged in a helical path about the sleeve. At both ends of each of these openings, there are provided bearing blocks 35 for the shaft 36 of a pressure roller 37, shown more particularly in FIG. 5.
- Each of these pressure rollers which may be of a tough resilient plastics material, is formed with a series of equally spaced circumferential grooves 38 separated by annular ribs 39 of which two succeeding ribs, indicated at 39a, are of somewhat lesser diameter than the others.
- Each of the rollers 37 extends for some distance through its opening 34 to approach, but not contact, the rotatable core 20.
- the roller shafts 36 are engaged in the bearing blocks 35 for adjustment, radially with respect to the core 20, by means of adjustment screws 40.
- the tube forming strip 41 shown in section in FIG. 5, is an extruded strip with a base 42 with side flanges 43 having hooked extremities, and with a series of T-section flanges 44 between the side flanges 43 in equally spaced arrangement corresponding to the spacing of the pressure roller grooves 38.
- a roll (not shown) of the tube forming strip 41 may be carried on a reel (not shown), from which an end of the strip is carried to a strip guide 45 mounted in front of the base plate 10, in laterally adjustable manner, on a pair of brackets 46.
- the strip guide 45 directs the tube forming strip downwards and more or less tangentially, with respect to the outer sleeve 18, to pass through the opening 34 of one of the pressure rollers 37 and between that pressur roller and the rotatable core 20.
- the strip guide 45 is also arranged obliquely, as shown in FIG. 1, to direct the tube forming strip to the helical path along which the pressure rollers 37 are arranged and onto that part of the core 20 encircled by the rubber or like girdle 23.
- the tread of this girdle is in the form of grooves which are substantially parallel to the axes of the pressure rollers 37.
- Rotation of the core 20 causes the tube forming strip 41 to pass around the core in a helical path so that, after the completion of one rotation of the core 20 two parts of the strip lie closely adjacent, as shown in FIG. 5, the adjacent hooked side flanges 43 of the two parts of the strip being located in the groove 38 between the two reduceddiameter annular ribs 39a of a pressure roller 37.
- the opening 34 through which the tube forming strip 41 is introduced from the strip guide 45 is of increased width, as shown in FIG. 1, to give easy entry; and the far edge of each of the openings 34 is bent outwardly, as shown particularly at 46 in FIG. 3, to ensure that the strip, during its travel, does not become blocked, but is guided between the core 20 and the outer sleeve 18.
- a locking strip 47 which may be fed from a reel (not shown) to a locking strip guide 48 adjacent to the strip guide 45.
- the locking strip 47 as shown in FIGS. 5 and 6, is of open arrow-head configuration, with oppositely directed base flanges, and is capable of being pressed down onto, and locking together, the two adjacent hooked side flanges 43 of the two parts of the tube forming strip 41.
- the locking strip is applied by feeding it, from the locking strip guide 48, through the opening 34 of the first of the pressure rollers 37 and between its annular ribs 39a, the reduced diameters of which allow for the thickness of the base flanges of the locking strip superimposed on the base portions 42 of the adjacent tube forming strips 41.
- glue be introduced into the open arrow-head part of the locking strip. This is done by a glue nozzle 49 extending radially into the round-section passage 50 in the locking strip guide 48 through which the locking strip passes.
- the glue pump 32 draws glue from a reservoir (not shown) by way of a hose 51 and delivers it under pressure to the nozzle through a hose 52.
- the helically wound tube forming strip 41 With continued rotation of the core 20 the helically wound tube forming strip 41, its adjacent convolutions locking and adhesively secured together by the locking strip 47, form, between the rotating core 20 and the outer sleeve 18, a tube of which the internal diameter is determined by the diameter of the core.
- This tube as it is formed, is expelled from the open end of the outer sleeve 18, the treaded girdle 23 preventing circumferential slippage on the core but allowing axial slippage of the formed tube over the core's girdle and its polished front part.
- the working parts of the machine behind the base plate 10 are shielded by a chain guard 53.
- the machine may be used to line a sewer.
- the machine may be lowered by a winch or the like into a manhole, aligned with the sewer, and put into operation to form a lining tube which is impelled forwardly into the sewer. Because of its compact form the machine can be installed for this purpose without deepening or widening the manhole. If it is required to produce a tube of greater or lesser diameter from the strip, the machine may be quickly and easily modified by the interchanging of the core 20 and outer sleeve 18 (with its associated parts) for others of larger or smaller diameter.
- the core may be removed by unbolting its median plate 22 from the main shaft flange 17, and the outer sleeve may be removed by unbolting its internal flange 19 from the base plate 10.
Abstract
La machine décrite sert à enrouler des flancs de tubes en forme de bande (41) du type comportant des rebords latéraux (43) avec entre eux des rebords intermédiaires (44). La bande (41) est acheminée dans un espace annulaire (21) situé entre un manchon cylindrique externe (18) fixé à une plaque de base (10) et un noyau cylindrique guidé (20) tournant de façon coaxiale à l'intérieur du manchon (18). Une série de cylindres de pression (37) sont montés le long d'un chemin hélicoïdal sur le manchon (18) et pénètrent chacun dans l'espace annulaire (21) par une ouverture (37) ménagée dans le manchon, l'une desdites ouvertures constituant une ouverture d'entrée pour la bande (41). Les cylindres (37) pressent la bande (41) en prise frictionnelle avec le noyau rotatif (20) et la guide pour qu'elle forme une hélice avec des circonvolutions étroitement adjacentes. Une bande de blocage (47) longitudinalement évidée est également acheminée dans l'espace annulaire (21), les cylindres (37) pressant ladite bande en prise de blocage avec les rebords latéraux adjacents (43) de circonvolutions successives de la bande enroulée hélicoïdalement (41).The machine described is used to wind flanks of strip-shaped tubes (41) of the type comprising lateral flanges (43) with intermediate flanges (44) between them. The strip (41) is conveyed in an annular space (21) located between an external cylindrical sleeve (18) fixed to a base plate (10) and a guided cylindrical core (20) rotating coaxially inside the sleeve (18). A series of pressure cylinders (37) are mounted along a helical path on the sleeve (18) and each enter the annular space (21) through an opening (37) formed in the sleeve, one of said openings constituting an inlet opening for the strip (41). The cylinders (37) press the strip (41) in frictional engagement with the rotary core (20) and guide it so that it forms a helix with closely adjacent convolutions. A longitudinally hollowed blocking strip (47) is also routed in the annular space (21), the cylinders (37) pressing said strip into blocking engagement with the adjacent lateral flanges (43) of successive convolutions of the helically wound strip ( 41).
